HAND-WHEEL.

Specification of Letters Patent.

Patented Aug. 6, 1907.

Application filed June 18, 1906. Serial No. 322,193.

To all whom it may concern:

Be it known that I, ALEXANDER M. Gow, a citizen of the United States,residing at Duluth, in the county of St. Louis and State of Minnesota,have invented certain new and useful Improvements in Hand-Wheels; and Ido hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

My invention relates to wheels and has special reference to the class ofwheels known as hand wheels. The essential elements of a hand wheel arethe hub, the rim and some rigid connection between the hub and the rim.The rigid connection usually consists of two or more spokes. In orderthat a hand wheel may be securely fastened to a spindle, it is necessarythat the hub be of considerable thickness; the spokes must be ofsufficient strength to withstand not only the torsional stress to whichthey are subjected in the normal opera tion of the wheel, but also theunusual and excessive stresses that occur in case a wrench or hammer isused to start the wheel. It is very desirable that the rim be soconstructed as to afford a good grip for the hand, to avoid slipping inthe grasp and to avoid cutting the hand, and it is also desirable thatthe construction of the rim be such that it will not become hot in casethe wheel is used on a valve controlling the flow of hot fluid. Themerits of this invention lie in the fact that all these characteristicsare incorporated in a wheel of this construction.

The invention consists of the constructions, combinations andarrangements of parts hereinafter described and claimed.

Referring to the drawings, Figure 1 is a plan view of the material ofthe wheel as stamped from a thin sheet of metal. Fig. 2, is a plan viewof a finished wheel. Fig. 3, is a section of the wheel on the line AB ofFig. 2. Fig. 4, is a section of the wheel on the line OD of Fig. 2. Fig.5, is a plan view of a modified form of said wheel. Fig. 6, is a sectionof said modifled form of the wheel, on the line EF of Fig. 5.

Similar figures refer to similar parts in all the figures.

1, is a ring, having outwardly directed radial fingers,

2, formed thereon. A diametrically directed strip 3 extends across thecenter of said ring and has formed thereon the Wings 3*, from whichrings extend the lugs 4. The strip 3 is preferably apertured at itscenter, the contour of said aperture preferably being non-circular as at3 In the finished wheel, the radial fingers, 2, are bent to tubular, ornearly tubular form, to

- compose a practical and convenient rim, most clearly as shown in Figs.3, 4, and 6. The wings are bent on the lines GH, and I-J of Fig. 1, andthe lugs are bent on the lines KL, and MN of Fig. 1, so as to cooperatewith the central portion of the strip 3 to form the hub of the wheel,the construction being such that a considerable space will exist betweenthe lugs 4 and the central portion of the strip 3, thus providing therequired thickness for the hub.

In the modified form shown in Figs. 5 and 6, the strip 3, is, at itscenter, pressed oppositely from the direction in which the wings arebent, so as to form a recess 6 for the reception of one end of a nut 7,or equivalent filling for the space between said lugs 4 and the body ofthe strip 3. When said lugs 4 are bent toward each other from oppositesides of the plane AB of the wheel shown in Fig. 2, or from oppositesides of the plane EF of the wheel shown in Fig. 5, they cooperate toinclose a passage 8 for the spindle (not shown), upon which said wheelmay be mounted. The construction of the wings is such. that when bent toform the finished wheel, they will be approximately V shaped inlongitudinal section. It will be obvious that the portions of the strip3 between the hub and the ring 1, operate as spokes and that the bendingof the wings at right angles to the plane of the strip 3 produces aU-shaped cross section of great strength. The ring 1, is shown asdished, which form is preferably adopted as affording greater strength,and also for the reason that the hand is in such case more readily keptfrom contact with the center of the wheel.

Having now described my invention, what I claim is,

1. A single piece wheel comprising a ring, an outer rim of tubular crosssection, spokes, and a hub whose one end iscomposed of metal bent intoparallelism with its other end and spaced therefrom.

2. A wheel comprising a ring, a series of radially disposed fingersintegral with said ring and extending ontwardly therefrom and forming arim of greater thickness than the material of which said ring andfingers are composed, spokes integral with said ring, and a hub integralwith said spokes, said integral hub being of greater thickness than thematerial of which it is composed.

3. A wheel comprising a ring, a series of radially disposed outwardlyextending lingers integral with said rim and forming a rim of greaterthickness than the material of which said fingers and ring are composed,spokes integral with said ring and of greater thickness than thematerial of which they are composed, and a hub integral with saidspokes, said integral hub being of greater thickness than the materialof which it is composed.

In testimony whereof I hereunto affix my signature, in presence of twowitnesses.
